X and Y Series I/O Board Model List

Multi-Protocol Network Integration

Function Implementation
Video Surveillance:
Hardware: Quad-core Cortex-A53 + GPU processes 1080p/4K video; 1TOPS NPU supports face/license plate recognition; HDMI, USB, 4G/5G modules for video transmission.
Software: Ubuntu + OpenCV for AI algorithms, RTSP/MQTT for cloud upload (e.g., Alibaba Cloud).
Application: Multi-channel camera monitoring, real-time face/license plate recognition, local storage or remote viewing.
Access Control:
Hardware: X-board (RS485/RS232) connects RFID readers, Y-board (DI/DO) controls locks; Ethernet/4G for networking.
Software: BLIIoTLink integrates Modbus/MQTT, Node-RED for access logic.
Application: Face/card-based door access, events uploaded to property management platform.
Intrusion Detection:
Hardware: Y-board connects PIR/vibration sensors; NPU analyzes anomalies.
Software: Node-RED processes sensor data, MQTT uploads to cloud.
Application: Detects unauthorized entry, reduces false alarms with video integration.
Alarm Function:
Hardware: Y-board (relay/PWM) controls buzzers/lights; 4G for notifications.
Software: BLIIoTLink sends alarms to SCADA, BLRAT for remote management.
Application: Triggers sound/light alarms on anomalies, notifies security personnel.

Advantages
